Today, @kinnison and I have moved the Subplot project from gitlab.com to Radicle.

Subplot is our tool for documenting acceptance criteria and how they are verified for all stakeholders of a system. Coincidentally, Subplot can also generate code to perform the verification.

The new location is here:

We’re now scoring wireless headphones! We evaluated 14 popular models using a new scoring rubric. The results highlight a clear gap between what’s possible and what’s currently being built. Let us know which headphones you'd like to see scored and read our blog at the link below!

The year is 2026, and my 8x2GHz 8Gb RAM pocket device ("phone") can't play a 128 kbps mp3 (pre-downloaded) over Bluetooth without sound glitches every minute

ADDENDUM: Now also a blog post at https://jan.wildeboer.net/2026/05/PSA-CopyFail-CVE-2026-31431/
PSA on Copy Fail (CVE-2026-31431)

This is a short PSA (Public Service Announcement) on how I dealt with the Copy Fail vulnerability. This will be updated as soon as the updated kernel packages are made available. This is a pragmatic post on how to deploy a mitigiation RIGHT NOW.

Ah, the #copyfail clickbait posts are coming. Here’s my serious contribution. On your Linux machine add

initcall_blacklist=algif_aead_init

to your kernel boot commandline (typically in grub). Reboot. You are now safe until the updated kernel packages become available. For distributions with the `grubby` command this is done as root with

# grubby --update-kernel=ALL --args="initcall_blacklist=algif_aead_init"

This mitigation comes courtesy of Red Hat. Our engineers keep you safe :)

So CopyFail CVE-2026-31431 is a thing.

If you're on the Ubuntu platform, 26.04 is not affected. 18.04 through 25.10 are indeed affected, but no fixes are available.

If you're on another platform, check with your vendor for update availability.

Unlike what the buffoons at Theori published as a "mitigation", the folks at Red Hat actually published a viable mitigation for CopyFail CVE-2026-31431.

Specifically, edit your grub (or whatever you use to load your kernel) configuration to have one of the following arguments:
initcall_blacklist=algif_aead_init
initcall_blacklist=af_alg_init
initcall_blacklist=crypto_authenc_esn_module_init

With such boot arguments to the Linux kernel, the affected bits won't be reachable.

That was the most uneventful system version upgrade I ever did. Download, reboot, install, done. I can go on about my day.

And everything still works and is set up exactly how it was. The whole process took ~30 minutes.

Imagine!
